both those guys suck. The 2nd one has been around forever, usually with Joe Webb, who has a similar getup. I think he's from Argentina and has some bitterness about something that happened there, but I'm not sure about his ideology. It's hard to know how to drive them away. I think they threaten to press charges for being attacked. The first person has negative -100 karma points. My grandmother always referred to people needing to be taken down a notch. Hopefully they aren't involved in education or childrearing.

the 2nd photo is a random wingnut with an obviously hand-made sign. yes, his anti-semitism should be called out, but it's different from the first photo. the sign about tristan looks like multiple persons had a hand in crafting that sign, from the original artist to the printmaker who enlarged it to the woman who waved it. it's evidence of an entire community cruelly mocking the injury of a supporter of Palestine, and using a decent amount of economic privilege in order to do so (signs like that aren't cheap).
